How can I use the READPAST hint in NHibernate?

问题

Is there any way I can get NHibernate to use the READPAST hint when selecting data from SQL Server?

回答1:

Option #1 Easy way: SQL query

Session.CreateSQLQuery("select * from YourEntityTable with (readpast) where SomeColumn = :col")
.AddEntity(typeof(YourEntity))
.SetString("col", value)                            
.UniqueResult<YourEntity>();

Option #2 Requires more work:

If you're not using one of NHibernate.LockMode you can override dialect's AppendLockHint() to something like:

public override string AppendLockHint(LockMode lockMode, string tableName)
{
    if (lockMode == <lockModeYouWantToSacrificeForThis>)
    {
        return tableName + " with (readpast)";
    }
    return tableName;
}
